Rachel reached into the box and pulled out a pair of black panties. She blushed and looked around to make sure he mother hadn't seen her open the box. She quickly hid the box somewhere that her mother couldn't find it and she took the panties up to her room.
She closed and locked the door, and then turned her attention back to the underwear. Now that she had a chance to really look at it, she noticed it was much more expensive looking than she had first thought. They seemed to be made out of some kind of extremely silky lace or something. She just stared at them for a few minutes until curiosity finally made her try them on.
She undressed and slowly slid them up her legs, and putting them on snuggly over her crotch. Thy fit perfectly and she was amazed at how incredible they felt. It was like she wasn't even wearing anything.
She looked at herself in the mirror and made a few sexy poses. She looked good in them too.
"Wait, I have just the thing." She muttered, opening her closet and digging through it as she mumbled.
"Aha. Here it is." She pulled out a black bra that wasn't made of anything close to the same material, but it went well with the panties. She had a little bit of trouble putting the bra on.
"That's wierd." She said when she finally got it on. "I don't remember that bra being so hard to get on." She looked closely at her reflection. "That's really strange. Are my breasts bigger?" She cupped them in her hands. "Nah." She shook her head. She was just imagining things. Her breasts couldn't just grow that fast. She decided to keep the bra and panties on and she put on a dark red tube top that accentuated her moderate C cup breasts. She picked out a sexy, tight black miniskirt to go with the top. She wasn't sure why. She usually dressed more conservatively. "Well, I still look drop dead gorgeous." She blew her reflection a kiss and went back downstairs. She wrote a note for her mother that said she had decided to go out for the day and she would be back by dinner or later.
She grabbed her purse and left, not noticing the strange tingling sensation that was coming from her chest and crotch.
